Patent CA-2159094-A1 (CA)
Title: Tin-acrylate-containing polymers as algicidal agents in building materials
Inventor: BIGHAM WILSON STUART
IPC: A01N55/04
Filed: 1994-02-18
Abstract: Granular materials having a tin-acrylate polymer coating are described which are algae-resistant. A method of inhibiting the growth of algae on roofing granules and other particulate materials attached to substrates by the use of tin-acrylate-containing polymers either as a topical treatment or as a polymeric binder is also presented. The methods presented are an advancement in the art in that in addition to algae-resistance, the polymers also confer other desirable properties to the granules onto which they are coated, such as increased adhesion to asphalt shingles.

Patent CA-2165497-A1 (CA)
Title: Toilet with water saving, vacuum-assisted flushing apparatus and associated methods
Inventor: HAYMAN DENNIS J
IPC: E03D11/02
Filed: 1995-12-18
Abstract: A tank type toilet has a water saving, vacuum-assisted flushing system that incorporates a diverter valve disposed in the tank portion of the toilet.  During the flushing of the toilet, pressurized water is discharged from a ballcock valve assembly in the tank and delivered to the diverter valve which creates from the received water a water jet that is used to create a vacuum area within the diverter valve.  The vacuum area is communicated with an uppermost interior portion of the bowl trapway to facilitate a main flushing action in the bowl that requires less flushing water.  At the same time, the water jet entrains tank water therein, through water inlet openings in the diverter valve body, and delivers the jet and entrained water to the rim flushing passage of the bowl to augment the vacuum-assisted main flushing action.   When the tank water level falls to a predetermined level, a float assembly on the diverter valve acts through a poppet valve therein to terminate the jet and divert water flow through the diverter valve to refill the tank and bowl,  thereby readying the toilet for another flush cycle.
Patent CA-2166779-A1 (CA)
Inventor: DAHMEN KURT
IPC: C08F8/00
Filed: 1994-06-28
Abstract: The invention concerns powder-form, water-swelling cross-linked polymers with a high capacity for absorbing, under pressure, aqueous liquids, in particular body fluids, the polymers being made from (a) monomers containing 55-99.9 % by wt. of acid groups of which at least 50 mole % have been neutralized; (b) 0-40 % by wt. of monomers copolymerizable with (a); (c) 0.1-5.0 % by wt. of at least one cross-linking agent and (d) 0-30 % by wt. of a water-soluble polymer. The cations of the salts covered by (a) include Li+ and Na+ but preferably K+, Cs+ and Rb+ plus primary, secondary or tertiary methylammonium ions, alone or in combination. The polymers are prepared by reacting the monomers together with a carbon dioxide expanding agent, drying the polymer thus formed and then heating it to a temperature of 100-300°C with one or more compounds capable of reacting with the polymer to cross-link the surface layer. Polymers of this kind are suitable for use as components of nappies, sanitary towels and incontinence pads, as components of current- and light-carrying cables, as soil-improvement agents and artificial earth in plant cultivation and as packaging materials.

Title: Shredding apparatus with shearing action
Inventor: DESCHAMPS MAURICE
IPC: B02C18/14
Filed: 1993-09-20
Abstract: A shredding apparatus includes a rotor having rows of tines projecting generally radially outwardly therefrom, and also a housing surrounding the rotor having rows of tines projecting generally radially inwardly therefrom. The rotor tines and stator tines have staggered positions, with one or more of the rotor tines passing between adjacent stator tines. Material inserted into an inlet at the top of the housing is caught by the rotor tines and pulled past the first row of stator tines. The first row has fewer tines than does each row of tines on the rotor, whereas the final row has the same number of tines as each row on the rotor. The opposing faces of the tines of the rotor and stator are flat, with a small clearance between passing tines, of typically about 1/8 of an inch. The passing flat faces on the tines are at a slight angle to each other, the outer ends of rotor tines passing stator tines ahead of the inner ends in a scissors-like fashion. The rotor speed is a function of the material being shredded, and has a value of at least 500 rotations per minute. A multi-stage shredding assembly may be created in which the output from one shredding apparatus feeds another shredding apparatus.
